DEPOSITING IIIACHINE.

Application filed January 3, 1922, Serial No. 526,498.

T 0 all to 710m it may concern:

Be it known that I, Fnnnnnlon "vVnsrnR- MAN, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and tate ofIllinois,- have invented certain new and useful Improvements inDepositing of which I do declare the following to be a full, clear, andexact description, reference being had to the accompanying drawings,forming a part of this specification. t V

This inventionhas relation to depositing machines of that type in whichconfections such as marshmallow, chocolate, jelly or the like, aredeposited upon the surfaces of cakes that are advanced in successiverows beneath the depositing mechanism. This type of machine is set forthin Letters Patent No. 1,121,434, granted to me December14, 1914, andNo.1,392,034, granted to me Sep tember 27, 1921. As the present inventionrelates particularly to the means employed for depositing the confectionupon the surfaces of the cakes and as such means is ap pli'cable tomachines such as are set forth inmy aforesaid patents, I have not deemedit necessary to illustrate in detail the main frame of the machine, themechanism for feeding the rows of cakes to the depositing I mechanismnor the other parts which are found in my prior patented machines andwhich will be readily understood by those familiar therewith. V v

The present invention consists in the features of novelty hereinafterdescribed," illustrated in the accompanying drawings and particularlypointed out in the claims at the end of the specification. p V Figure 1is i a view in central vert cal section through the hopper or receptaclefor containing the confections to be deposited,

and through the parts associated therewith, certain parts being shown nelevation.

As shown, thereceptacle A consists of upper and lower portions bolted together, thereceptacle being preferably divided into two separate and by a verticalcompartments 15 and 16, diaphragm or partition fections of differentkinds for coating the cakes. The bottom a of the receptacle is formedwith achannel ex tending from end to end thereof to receive 17, so thatcon- 'a die-carrier plat e B that carries the dies or nozzles, thisdie-carrying plate being preferably formed with beveled side walls toengage the corresponding beveled walls of saidchannel. The die-carryingplate B is formed with a sponding in number to the dies or nozzlesemployed and through each oftheseopenings projects one of the dienozzles 20. Each of the nozzles 20 is shown as formed at its upper endwith a flange 21 (see F ign 5) adapted to rest upon an annular shoulder22 of the die-carrying plate B. The upper part of each of the. openings.in the diec'arrier plate B is formed with ,an'expanded portion toreceive a diskor plate 23 that rests'upon the shoulder-'24 of thedie-carrier plate 13 and is held in'position by means of the screw 25.

of this vertical channel 27 connecting with thecross channel 28 thatcommunicates with an opening 29 in the top' ofthe disk, or plate 23 andpreferably also with a semi; cylindrical cutaway space or-channel 30 inthe die-carrier 7 Through the disk or plate 23 are also formed the holesor ports 31 that communicates: with the chamber 32 of thedie-carrierplate' that passes over a From the disk or plate 23' dependsa hollow post 26 having a vertical channel 27 formed therein, the uppervend plate'B. (see Figs. 5 and 6).

may be employed series of openings corre immediately above the flangedtop of the die or nozzle 20. When in position for use, the disks orplates 23 are in line with the upper surface of the die-carrier plate B.

Above the die-carrier plate B, with itsdisks or plates 23,8Xl1611ClS thepartition plate or diaphragm 34 and on the opposite sides of thisdiaphragm 34 are arranged the slide valves G and C that control the flowof the confections from the compartments 15 and 16 of the receptacle A.The construction of the slide valves C and C is substantially the sameas in my before mentioned Letters Patent and these slide valves areprovided with a series of passages through which the confections willpass. The passages 0 1n the valve Q will correspond in arrangement andnumber with the ports or passages 31 in the plates 23 (see Fig. 6) whilethe passages c. in the valve C will correspond in number and arrangementwith the channels 29 and 30 through which material will pass from thecompartment lb of the receptacle A. The receptacle A. will be providedwith suitable mechanism, such as valves or casings D and long plungers Einclosed therein; but as these form no part of the present invention andare fully set forth. .in my said Letters Patent No. 1,392,034, they neednot be more particularly described herein. The valves (1, C arereciprocated longitudinally by suitable connections attached to one endthereof. such for example as the vertical shaft 40 (see Figs. 2 and 4)the upper end of which is connected by an arm 41 to the valves'C and C,while its lower end is provided with an arm42 carrying a pin 43 thatengages a cam wheel 44 on the cross shaft 45, as in my before mentionedLetters Patent. r

The tubular post 26 is provided at its lower end with reducedscrew-threaded portion 2b upon which is mounted a correspondinglythreaded conical valve seat 26 i the bottom of which is preferablyconcave, as

at 26, for a purpose to be presently stated.

Aroundeachof the die nozzles 20 fits a vertically reciprocating. tubularvalve or sleeve having a flange 51 atits upper end from which flangeproject the lugs-or trunnions 52 that willbe engaged bythe yokeshapedarms 53 that project'from a rocking plate The rocking plate: 54 isprovided at its ends with reduced circular portions 55 and 56 that arejournaled in suitable bear ings 57 and 58 secured-to the under side ofthe die-plate carrier B, (see Figs. 1 and 2).

Tothe end of rocking plate 54 is connected a rock arm 59 that is unitedby a link 60 to a pivoted rock arm 61 -(see that carries at one end aroller adapted to travel upon and be. actuated by the cam wheel 62. Themechanism for operating the rocking plate54 is substantially the same asin my before mentioned, Letter Patent and need is also beveled andextends approximately to the plane of the periphery of the seat 26 lVhen a row of cakes has been brought by the carrier belt 12 beneath thedies or nozzles and has been lifted by the table 13 (in manner wellunderstood), the valve D in the ompartment 15 of the receptacle A. willtie scend and cut off the passage of marshmallow, and the long plunger Ein the valve D will then descend and force the marshmallow beneath itdown and through channels 36, channels a, valve C and ports or channels31 (see Fig. 6), it being understood that at such time the valves 50will be lifted to permit the passage of the marshmallow over the valveseats 26 On to the cakes. Preferably, however, the valves 50 are notlifted until a slight pressure is created within the nozzles 20, as thisinsures a quick and compact discharge of the marshmallow from thenozzles onto the cakes. At the time that the marshmallow is being thusforced onto the cakes, the valve D in the compartment 16 of thereceptacle A, will move downward and close against its seat so-a's tocut off the supply of jelly or like confection at such point, and thelOng plunger E in the compartment 16 will then descend and force thejelly through the channels 37. the ports 0" of the valve C, the channels30 and 28 into and through the vertical channel 27 of the hollow posts26. The operation of the valve D and plunger E is preferably so timedthat the beginning ofthe discharge of marshmallow. onto the cakesthrough the nozzles 20 will occur slightly before the plunger in thecompartment 16 of the receptacle A descends to expel the jelly or likeconfection through the tubular posts 26. When the mashmal-low and jellyhave thusbeen deposited onto. the cakes. the valves 50 will be closedand the slide valves'C and C will be shifted to cut of'fthe flow ofconfections through the channels 36 and 37. after which the row of cakeswill be lowered and the car'-.

rier belt 12 will be advanced in manner well ratus is designed fordepositing one kind of confection only upon the surface of the cakes;hence, in this form of the invention, 7

' nel to receive such plate.

of confection. The plate 23* may be a can:

tinuous plate extending above all the diesor nozzles, and in such casethefdie 'carrier plate B will be formed with ana-ppropriate cha n I amaware that machines for dropping dough or batter into pans haveheretofore been constructed, in which-the die nozzles were-provided withvalve seats ana'vaivesg but in such prior machinespt re operation of thevalves th at control the flow of material' through the nozzleswasef'fected by and depended upon the lifting of the table whereon the pansrested. With my present invention. the valves that control the flow ofmarshmallow through the nozzles are ac tuated by mechanism independentof the table by which the cakes to be coated are lifted towards the diesor nozzles; and hence not only may a more rapid and effective dis chargeof the confections onto the cakes be secured, but the operation of thesevalves can be so timed that the flow of marshmal low shall not beginuntil the cakes are at exactly the right elevation and the flow can becut off independently of the downward movement of the table and asquickly as desired to make sharp and cleandeposits.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is V 1.
